Lateral via trochanteric flip

Trochanteric-flip osteotomy

To identify the distal starting point of the trochanteric-flip osteotomy, the vastus lateralis is elevated from the proximal femur up to its insertion at the greater trochanter.

The proximal end of the trochanteric-flip osteotomy should leave a 5 mm cuff of the posterior border of the gluteus medius attached to the portion of the trochanter that will remain on the shaft.

The trochanteric fragment should be approximately 1.5 cm thick (a thinner fragment can break and is difficult to reattach, a thicker fragment risks encroaching into the piriformis fossa leading to vascular damage).

The risk of injury to the medial femoral circumflex artery can be reduced by following this recommendation.
